关于分散布置的微机保护测控装置的探讨

对目前电力系统的分散布置的保护测控装置的优缺点进行了全面的分析。针对分散布置的保护测控装置存在的保护、监控、低周减载、小电流接地检测及通信网络的可靠性等问题提出了相应的解决方法．即分散布置的保护测控装置只承担和完成与自身相关的保护、监控功能。而将需由系统来统一解决的低周减载、小电流接地检测、电压无功自动调节等问题交还给监控系统来完成。同时对分散布置的保护测控装置在实际运行管理中碰到的问题进行了剖析，并展望了其发展远景。

Discussion of the Dispersed-installed Digital Protection and Monitor Device

On the basis of the overall analysis for all the advantage and disadvantage of the popular dispersed- installed protection and monitor device,aiming at all the existing problems,such as protection,monitor and control,low frequency unloading,low-current grounding check and communication network reliability,relevant methods are introduced. The dispersed- installed device only accomplishes its related protection and monitoring function,while other functions left to the monitoring system. Meanwhile,the questions in device application are discussed,and its perspective future is predicted.
